COIN-CONTROLLED LIQUID-'DISPENSINGu APPARATUS- SIEECIFICATION forming part o f Letters Patent No. 768,509, dated. August 23, 1904.

Application iled April 20, 1903.

Serial No. 153,426. (No model.)

To all whom, it 1v1/ay concern:

Be it known that I, ARTHUR FRANKLTN BRAD- sHAw, a citizen of the United States, and a resident of Bieber, in the county of Lassen and State of California, have invented new and .useful Improvements in Coin-Controlled `Liquid-Dispensing Apparatus, of which the following is a full, clear, and exact description.

This invention relates to a coin-controlled liquid-dispensing apparatus; .and the object that I have in view is the provision of a sim- .ple mechanism wherein liquid may be drawn from a suitable container on the deposit of a suitable coin or slug, the volume oi' the escaping liquid being regulated automatically by' the operation of a suitable knob and the coin or slug being discharged automatically into a suitable receptacle, so that the coin will not subsequently interfere with the proper service of the machine.

Further objects and advantages of the invention will appear in the course of the subljoined description, and the novelty will be defined by the annexed claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1` is a sectional perspective view through a portion oi' a liquid-dispensing apparatus embodying my invention. Fig. 2 is a longitudinal section through the valved liq'- uid-conduit, on an enlarged scale; and Fig. 3

is a plan view of the hand-operated slide removed i'rom the machine'.

` A designates a portion of a casing for inclosing the operating parts of the coin-controlled liquid-dispensing apparatus of my invention. The upper portion of this casing is provided with a coin chute or passage a, which opens vertically through a ledge or shoulder a' of said casing in order to present an opening for the introduction of a coin o r slug. Within this casing isprovided a horizontal plate or partition B, which is formed in its upper face with a channel or way b, having a smooth surface adapted to permit the coin or slug to travel freely thereon. In this partition-B is secured a vertical conduit 5, which is closed at its lower end by a head 6, as shown byFig. 2, and this conduit is adapted to be connected operatively with any suitable liquid-container by an intermediate pipe,

tube, 0r hose, (not shown,) whereby the liquid may be transferredV by gravity from the container into the conduit 5. From'the lower part of this conduit leads an exit-pipe 7 which is preferably attached to the lower portion of the conduit at a point above the head 6 thereof, as shown by the drawings.) Thisk exitpipe extends through the casing A, and-it may be provided with a faucet or stop-cock 8. I do not desire to limit myself to the employment of this stop-cock, because in-dispensing certain liquidsthe cock may be omitted; but when the apparatus is used for dispensing charged liquids I find it advisable to employ ythe stop-cock, the stem. of which is arranged 13 andV allow the liquid to pass from the up per part of the conduit 5 into the chamber 11. The other partition, 10, of said conduit is similarly provided with a vertical passage 16, across which extends a valve 17 ,the latter having a liquid way or port 18.` (See Fig.- 2.) The valves 14 17 are of the variety known 'as plug-valves, the same being tapered and seated in tapering passages which extend across the partitions 9 10, respectively. Each valve is held snugly to its'seat by any suitable means, such as the nut 19, attached to one end of the valve, and from the other end of said valve extends a stem 20, on which is secured a spur gear-wheel 21. I would have itk understood, however, that I do not limit myself to any particular type or' valve; but the form of valve herein shown is preferred because of its simplicity and eiiciency.

The stems 2O of the two Valves 14 17 extend from one side or' the conduit 5, and the gears 21 on said stems are disposed in the same vertical plane in order to have intermeshing engagement with a double rack, which is formed on or attached to a coin-controlled slide 22. This' slide 22 is disposed above the partition B in position to travel thereon, and said slide is provided at its rear portion with an eX- tended bar 23, the latter being of less width than the slide. The bar 23 is formed with gear-teeth on its upper and lower edges, and the slide 22 is arranged in the machine Jfor the rack-bar 23 to travel between the opposing edges of the gears 21, as shown by Figs. 1 and 2, whereby the slide 22 is geared to both of the valves 14 17 for the purpose of operating them simultaneously.

The slide 22 is provided in its under side A with a notch 24, and in rear of this notch said slide is formed with a vertical transverse coinslot 25, the latter extending entirely through the slide. The partition B is provided at its front portion with a vertical coin-passage 26, with which communicates an inclined coinchute 27, that depends Jfrom the partition B and is disposed within a chamber C at the bottom of the casing A, said coin-chute 27 having communication with a coin-receptacle D. The casingA is provided in front of the coinpassage 26 with a socket 28 and with an exposed slot 29. In this socket is arranged a slidable latch 30, which is provided with a linger-knob 31, that projects through the slot 29 and lies outside of the machine in a position for convenient access by the operator. Thislatch is normally pressed in an upward direction by a coiled spring 32, which is housed in the socket 28 in position for engagement with the lower end of the latch, said latch being held in engagement with the under side ot' the coin-controlled slide 22 and adapted for engagement with the notch 24 of said slide for a purpose which will hereinafter appear.

The partition B is provided with a socket 33 in rear of the coin-passage 26, and in this socket is arranged a detent 34, having a beveled upper face 35, said beveled end of the detent projecting normally into the coinway b under the action of a spring 36` which is housed in the llower part of the socket 33 in a position for engagement with said detent. The latch 30 and the notch 24 in the coin-controlled slide 22 are of less width than the detent 34 in order that said detent may ride against the under face or' the slide 22 without entering the notch 24; but when said slide reaches the limit of its forward movement the latch 30 is projected into the notch 24 by the spring' 32, thus locking the slide 22 in a forwardly-drawn position and preventing a repetition ot' the operation.

37 indicates a manually operated slide, which is housed or contained within the casing' above and in overlapping relation lo the slide 22. Said slide 37 is provided at a, point intermediate or' its length with a coin-slot33, adapted in the normal position ol said slide 37 to aline vertically with the coin-chute t and with the coin-slot 25 of the slide 22. (See Fig. 1.) The slide 37 is provided at its rear portion with a curved shank 39, arranged to extend loosely around the vertical liquid-conduit and to the rear extremity ot this shank is attached a coi led retracting-spri ng 40. which is secured in a suitable vay within the casing, said shank 39 ot' the slide 37 and the spring 40 being housed within a chamber IC. 'l`he spring 40 normally draws the slide 37 in a, rearward direction, and that part ol said slide between the coin-slot 33 and the conduit 5 should be long enough so that when the slide is fully withdrawn the inner end thereof will not pass forwardly beyond the coin-chute u, thus preventing a coin or slug which may be introduced when the slide is in its forward position from dropping in rear ol the slide and being pressed thereby into the chamber E or against the conduit ',lhe front end of the slide 37 is provided with a depending lip or shoulder 41, adapted to overlap the front end of the coin-controlled slide 22, and to this slide 37 is attached a normally exposed finger-piece 42, the same being shown in the form of a ring, although this may be changed, if desired.

The operation o1 the invention may be described as follows: lith the parts in the position shown by Fig. 1 the valve 17 of the conduit is adjusted for its liquid-way 13 to lie across the passage 16 and prevent the liquid contents or' the chamber 11 from passing into the chamber 12, while the valve I4 is adjusted for its liquid-way to have communication with the passage 13, thus placing the chamber 11 in communication with the liquid-container. The valves 14 17 therefore occupy positions wherein the ports thereol are at right angles to one another, one ot lsaid valves being in an open position and the other in a closed position. A coin or slug isnow introduced into the chute fr', and it drops into the coin-slots 25 38 of the slides 22 37, the edge ol said coin resting on the way and connecting the slides 22 37 operatively together. 'lhe operator may now manipulate the linger-piece. 42 to pull the slide 37 outwardly, this motion of the slide 37 being communicated by the intermediate slug or coin to the other slide, 22. The slides move simultaneously under t he pull on the linger-piece 42, thereby distending the spring 40 and making the rack 23 ot the slide 22 operate the gears 21, and thereby simullOO taneously turn the valves 14 17 so that the valve 14 will cutoff the further iiow of liquid from the container into the chamber 11, while the valve 17 assumes a position wherein the liquid may flow from saidk chamber 11 into the chamber 12 and thence through the eduction-pipe 7 to a suitable receptacle adapted to be placed below the faucet 8. In the forward movement of the slides 22 37 the detent will not enter the notch 24; but when the slides reach the limit of their forward lmovement the coin or slug is brought into line with the coinpassage 26 and the notch 24 of the slide 22 takes a position immediately above the latch 30, the spring 32 of which impels said latch into the notch, thus locking the two slides against further forward movement. The latch 30 has positive engagement with the slide 22, so as to release the coin from the pull or energy of the spring 40 and allow said coin to easily drop into the passage 26, from whence it passes through the chute 27 into the receptacle D. The function of the detent 34 is to prevent a coin from being carried in a backward direction with the slides; but this detent is adapted to be depressed when the coin travels against the beveled face 35 thereofV upon the forward movement of the slides.-

After the coin drops from the slides the latter may be returned to normal position by the energyof the spring 40; but before the slides can be returned the operator should press down on the linger-piece 31, thus withdrawing the latch 30 from the notch ofthe slide 22. The pull of the spring 40 on the slide 37 makes the lip or shoulder 41 act against the slide 22 in returning the latter to normal position simultaneously with the slide 37, and during this backward travel of the two slides the rack-bar 23 againv reverses the valves 14 17, so asr to cut off communication between the chambers 11 12 and permit the liquid to pass from the container into the chamber 11, thus placing the apparatus in condition for service again.
